Outputs in JavaScript

Overview

Outputs in JavaScript are used to display information to the user, often through alerts, HTML elements, or the browser console. Understanding output methods is essential for debugging and user interactions.

Key Concepts

• console.log(): Outputs information to the browser's console.
• alert(): Displays a pop-up message.
• document.write() and innerHTML*: Writes output directly to the HTML document or element.

console.log("This is a console message.");
alert("Welcome to the page!");
document.getElementById("output").innerHTML = "Hello, user!";

Common Mistakes

• Misusing document.write(): It overwrites the document, so it should be used sparingly.
